With the tech tree re-organization on it shoves the evaporation processing 1 tech into py1 when it is needed in automation science. It provides the recipe to turn slaked lime into lime, which is needed because you make slaked lime from the only recipe to make acetylene. Acetylene is needed to mine lead.

Basically means you can't mine lead until py1, which is bad :)

I'll look into moving this. In the meantime, you can make lime from limestone and coke and just store the slaked lime in a storage pond.

Evaporation processing 1 is once again in the automation science stage as of the latest update.

neat, thanks
